Abstract

Many tone-only pagers have a silent memory mode in which pages can be received but no alert is given until the user presses a switch to interrogate the memory. The user gets no indication that anything has happened. Even in a lamp-equipped pager, a silent flashing alert (pager or low battery) may not be noticed before it times out. Some pagers use a vibrator to get the user's attention in silent mode, but this is not feasible in all products. One alternative is to give a short, low-volume beep when a page is received or low battery is detected. This feature can be implemented as a code plug option in a microcomputer- based pager through a simple software algorithm.

AUDIBLE INDICATION OF STATUS CHANGE IN A PAGER WITH MEMORY by Marie Shanley and Fernando Gomez

   Many tone-only pagers have a silent memory mode in which pages can be received but no alert is given until the user presses a switch to interrogate the memory. The user gets no indication that anything has happened. Even in a lamp-equipped pager, a silent flashing alert (pager or low battery) may not be noticed before it times out. Some pagers use a vibrator to get the user's attention in silent mode, but this is not feasible in all products. One alternative is to give a short, low-volume beep when a page is received or low battery is detected. This feature can be implemented as a code plug option in a microcomputer- based pager through a simple software algorithm.

   For pagers with no lamp: If a page is received and the option is enabled, a X second beep is given. The page Is stored in memory. The same beep is given if low battery is detected. Later, when memory is interrogated, the audible page alert or low-battery alert is given.

   For lamp-equipped pager: When a page is received or low battery is detected, the X second beep is given first. Then the appropriate flashing alert will start. If the alert is allowed to time out, it can later be interrogated in either the silent or audible mode.

This X second alert, similar to what is done in some digital watches, should be sufficient to get the user's atte...
